Sia F. The Weeknd & Diplo: Elastic Heart

Following the great success of the first Hunger Games soundtrack, with the second installment, Catching Fire, Katniss and company appear to be setting their mark even higher.

The first single off the soundtrack was an original song by Coldplay, entitled "Atlas." Now, clearly showcasing the diversity of the soundtrack, comes "Elastic Heart" by Sia featuring The Weeknd and produced by Diplo.The pairing of the Australian alt-pop artist and Mr. XO himself seems surprising, especially atop Diplo's rattling instrumentals, but the results appear welcoming.

Listen to the track below and stay tuned for the Catching Fire OST due out Nov. 19, featuring Of Monsters and Men, The National, Lorde, The Lumineers, Ellie Goulding, and Santigold.
